Lets a resource server (or a client checking its own token, via
self-introspection) verify a token's active/me/client_id/scope without
needing to be tightly coupled to this token endpoint. Requires the
caller to present their own currently-active token as authorization,
per spec's requirement that the endpoint MUST require some form of
authorization. Inactive tokens get back only {"active": false}, no
detail on why, matching the privacy stance already used for
revocation.
Pulled the hash-and-lookup-active-token logic (now needed a third
time) into MicropubToken::findActive(), used by this, the revocation
endpoint, and VerifyMicropubToken.

Tokens now store a hashed row in micropub_tokens instead of being
self-contained signed JWTs, so a leaked or unwanted token can actually
be revoked. Since revocation already requires a DB lookup on every
request, JWT's stateless-verification benefit was gone anyway, so this
also drops the lcobucci/jwt dependency entirely.
